09d9e4d Avri Altman 30 October 2021, 06:23:01 UTC scsi: ufs: ufshpb: Remove HPB2.0 flows The Host Performance Buffer feature allows UFS read commands to carry the physical media addresses along with the LBAs, thus allowing less internal L2P-table switches in the device. HPB1.0 allowed a single LBA, while HPB2.0 increases this capacity up to 255 blocks. Carrying more than a single record, the read operation is no longer purely of type "read" but a "hybrid" command: Writing the physical address to the device in one operation and reading back the required payload in another. The JEDEC HPB spec defines two commands for this operation: HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and HPB-READ to read the payload. With the current HPB design the UFS driver has no alternative but to divide the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ. This causes a great deal of aggravation to the block layer guys who demanded that we completely revert the entire HPB driver regardless of the huge amount of corporate effort already invested in it. As a compromise, remove only the pieces that implement the 2.0 specification. This is done as a matter of urgency for the final 5.15 release.

61a9f25 Martin K. Petersen 28 October 2021, 03:42:02 UTC scsi: mpt3sas: Fix reference tag handling for WRITE_INSERT Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.

e20f80b Brian King 19 October 2021, 15:21:29 UTC scsi: ibmvfc: Fix up duplicate response detection Commit a264cf5e81c7 ("scsi: ibmvfc: Fix command state accounting and stale response detection") introduced a regression in detecting duplicate responses. This was observed in test where a command was sent to the VIOS and completed before ibmvfc_send_event() set the active flag to 1, which resulted in the atomic_dec_if_positive() call in ibmvfc_handle_crq() thinking this was a duplicate response, which resulted in scsi_done() not getting called, so we then hit a SCSI command timeout for this command once the timeout expires. This simply ensures the active flag gets set prior to making the hcall to send the command to the VIOS, in order to close this window.

4e5483b Adrian Hunter 18 October 2021, 15:10:04 UTC scsi: ufs: ufs-pci: Force a full restore after suspend-to-disk Implement the ->restore() PM operation and set the link to off, which will force a full reset and restore. This ensures that Host Performance Booster is reset after suspend-to-disk. The Host Performance Booster feature caches logical-to-physical mapping information in the host memory. After suspend-to-disk, such information is not valid, so a full reset and restore is needed. A full reset and restore is done if the SPM level is 5 or 6, but not for other SPM levels, so this change fixes those cases. A full reset and restore also restores base address registers, so that code is removed.

In the abort I/O routine, the driver miscasts a context pointer to the wrong data type and overwrites a single byte outside of the allocated space. This miscast is done in the abort I/O function handler because the handler works on both FC-GS and FC-LS commands. However, the code neglected to get the correct job location for the node. Fix this by acquiring the necessary node pointer from the correct job structure depending on the I/O type.

f5ef336 Adrian Hunter 22 September 2021, 09:10:59 UTC scsi: ufs: core: Fix task management completion The UFS driver uses blk_mq_tagset_busy_iter() when identifying task management requests to complete, however blk_mq_tagset_busy_iter() doesn't work. blk_mq_tagset_busy_iter() only iterates requests dispatched by the block layer. That appears as if it might have started since commit 37f4a24c2469 ("blk-mq: centralise related handling into blk_mq_get_driver_tag") which removed 'data->hctx->tags->rqs[rq->tag] = rq' from blk_mq_rq_ctx_init() which gets called: blk_get_request blk_mq_alloc_request __blk_mq_alloc_request blk_mq_rq_ctx_init Since UFS task management requests are not dispatched by the block layer, hctx->tags->rqs[rq->tag] remains NULL, and since blk_mq_tagset_busy_iter() relies on finding requests using hctx->tags->rqs[rq->tag], UFS task management requests are never found by blk_mq_tagset_busy_iter(). By using blk_mq_tagset_busy_iter(), the UFS driver was relying on internal details of the block layer, which was fragile and subsequently got broken. Fix by removing the use of blk_mq_tagset_busy_iter() and having the driver keep track of task management requests.

But when cxgb4 and csiostor are both being loaded in parallel via modprobe, there is a race when firmware upgrade is attempted by both the drivers. When the cxgb4 driver initiates the firmware upgrade, it halts the firmware and the chip until upgrade is complete. When the csiostor driver is coming up in parallel, the firmware mailbox communication fails with timeouts and the csiostor driver probe fails. Add a module soft dependency on cxgb4 driver to ensure loading csiostor triggers cxgb4 to load first when available to avoid the firmware upgrade race.

There are a couple of issues with the commit: 1. It causes deadlocks. 2. It causes the shost->eh_cmd_q list of failed requests not to be processed, ever. So revert it. 1. Deadlocks The SCSI error handler runs with requests blocked beginning when scsi_schedule_eh() sets SHOST_RECOVERY state, continuing through scsi_error_handler() callback ->eh_strategy_handler() until scsi_restart_operations() is called. By setting eh_strategy_handler to ufshcd_err_handler, the patch changed the UFS error handler to run with requests blocked, including PM requests, for the entire run of the error handler. That conflicts with UFS error handler existing synchronization with UFS device PM operations. The UFS error handler synchronizes with runtime PM by doing pm_runtime_get_sync() prior to blocking requests itself. It synchronizes with system PM by use of hba->host_sem, again before blocking requests itself. However, if requests are already blocked, then PM operations will block. So: the UFS error handler blocks waiting on PM + PM blocks waiting on SCSI PM requests to process or fail + PM requests are blocked waiting on error handling to finish = deadlock This happens both for runtime PM and system PM. Prior to the patch, these deadlocks could not happen even if SCSI error handling was running, because the presence of requests in shost->eh_cmd_q would mean the queues could not be suspended, which would mean that, should the UFS error handler run at the same time, it would not need to wait for PM or vice versa. Please note these scenarios are not just theoretical, they were found during testing on a Samsung Galaxy Book S. 2. ->eh_strategy_handler() must process shost->eh_cmd_q list of failed requests, as all other eh_strategy_handler's do except UFS error handler. Refer for example: scsi_unjam_host(), ata_scsi_error() and sas_scsi_recover_host().

These can only be changed if the backstore is user-backed, otherwise the kernel returns -EINVAL. This triggers a warning in the targetcli/rtslib code when performing a target restore that includes non-userbacked backstores: # targetctl restore Storage Object block/storage1: Cannot set attribute alua_support: [Errno 22] Invalid argument, skipped Storage Object block/storage1: Cannot set attribute pgr_support: [Errno 22] Invalid argument, skipped Fix this warning by returning an error code only if we are really going to flip the PGR/ALUA bit in the transport_flags field, otherwise we will do nothing and return success. Return ENOSYS instead of EINVAL if the pgr/alua attributes can not be changed, this way it will be possible for userspace to understand if the operation failed because an invalid value has been passed to strtobool() or because the attributes are fixed.

This happens when the __vmalloc() failed. Consider we are reporting 4096 zones, then we will have "bufsize = roundup((4096 + 1) * 64, SECTOR_SIZE)" = (513 * 512) = 262656. Then, __vmalloc() failure halves the bufsize to 131328, which is no longer aligned to SECTOR_SIZE. Use rounddown() to ensure the size is always aligned to SECTOR_SIZE and fix the comment as well.

But a review of other elements and warnings were also evaluated. This patch corrected several items in the original patch: - Using be32_to_cpu() on a be16 data type - cpu_to_le32() used on a std uint32_t (CPU) data type. Note: This is a byte array, but stored in LE layout by hardware at 32-bit boundaries.

Most of the arguments are pointers to data structures. But for the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event, the argument is an enum value, and the code is typecasting the void * to an enum generating the warning. Fix by converting the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event to pass a pointer to the enum, thus it's a straight-forward pointer dereference in the event handler.

In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

Many distributions add an entry in /etc/fstab for the ESP. We must ensure that mounting does not fail. The default code page for FAT is 437 (cf. CONFIG_FAT_DEFAULT_CODEPAGE). The default IO character set is "iso8859-1" (cf. CONFIG_NLS_ISO8859_1). So let's enable NLS_CODEPAGE_437 and NLS_ISO8859_1 in defconfig.
